Formula and method

Room revenue of 30,000 from 150 sold room-nights gives an ADR of 200. For 10 available rooms over a fixed 30-day month, the same revenue gives estimated RevPAR of 100.

ADR = room revenue ÷ room-nights sold; 30-day RevPAR estimate = monthly room revenue ÷ (30 × available room count)

Worked example

Enter these known values and leave the other values blank.

Room revenue in the reporting period: 30000 USD
Room-nights sold in that period: 150
Room revenue for the modeled 30-day month: 30000 USD
Rooms available each day: 10

Average daily rate (ADR): 200 USD
Estimated RevPAR over 30 days: 100 USD

Assumptions and limitations

ADR uses room revenue and sold room-nights for the same reporting period. A room sold on several nights is counted once for each sold night.
The second calculation uses total available rooms over a fixed 30-day month. It estimates revenue per available room-night, not ADR at an unknown occupancy rate.
Room counts must be positive whole numbers. Zero sold room-nights leaves ADR undefined; zero revenue with a positive count produces zero.
Use room revenue consistently, excluding unrelated food, event or other operating revenue. The 30-day estimate assumes the entered room count is available every day.

Common questions

Why can ADR be higher than RevPAR?

ADR divides by sold room-nights; RevPAR divides by all available room-nights, including unsold inventory. Under consistent definitions, RevPAR equals ADR times occupancy.

Can I use the second estimate for a 31-day month?

Its denominator is fixed at 30 days. It is therefore not the exact RevPAR for a 31-day reporting period.

References

Bookify labels the monthly-revenue calculation as a fixed-30-day RevPAR estimate: its denominator is available room-nights, although the captured source calls this an estimated ADR.
